Embodiment
Fig. 1 is the structural representation of the utility model one embodiment learning table.Fig. 2 is along A-A section view in Fig. 1 Figure.Fig. 3 is partial enlarged drawing B in Fig. 1.Fig. 4 is partial enlarged drawing C in Fig. 2.Fig. 5 is partial enlarged drawing D in Fig. 2.Fig. 6 is Fig. 5 Middle partial enlarged drawing E.Understand that in the present embodiment, study table is as shown in figure 1, the study table includes liftable with reference to Fig. 1-Fig. 5 Desktop 1, desktop fixed mount 2, and can continuous a wide range of adjusting table panel inclination angle governor motion.
Desktop 1 is fixed on desktop fixed mount 2 apart from the proximal hinge of user.Desktop 1 is close to user's Distal end can open different angle with the regulation of desktop governor motion.
Wherein described governor motion includes connector 3, trapezoidal screw 5, and first ushers to seat rolling bearing 12, and second ushers to seat rolling Bearing 10, trapezoidal nut sliding block 9 and wind 6 etc..
The dorsal part of desktop 1 is fixed with connection shaft seat 7.The upper end of connecting rod 3 is be hinged by the first bearing pin 8 and connection shaft seat 7; The lower end of connecting rod 3 is be hinged by the second bearing pin 11 and trapezoidal nut sliding block 9.
Together with trapezoidal nut sliding block 9 and the threaded engagement of trapezoidal screw 5.With first at first end-journal of trapezoidal screw 5 Usher to seat the interference fits of rolling bearing 12, and usherd to seat the axial lock of rolling bearing 12 by first.Trapezoidal screw 5 is close to the second end-journal Place ushers to seat the interference fits of rolling bearing 10 with second, and is usherd to seat the axial lock of rolling bearing 10 by second.In this way, trapezoidal screw 5 Rolling bearing 12 can only be usherd to seat around first and the second axis that the axle center of rolling bearing 10 is formed of usheing to seat rotates and do not had There is the straight-line displacement of any direction.
In the present embodiment, the second end of trapezoidal screw 5 makes hexagon deep hole, can be inserted wind 6. One usher to seat rolling bearing 12 and second usher to seat rolling bearing 10 rotationally supporting under, shake wind 6 can drive trapezoidal screw 5 Rotate, and then drive trapezoidal nut sliding block 9 to screw and make it along the axis of trapezoidal screw 5 and in connect base 4 Bottom surface is for linear motion, and desktop 1 is corresponding under the push-and-pull action of connector 3 rises or falls.
Trapezoidal nut sliding block 9 screws cooperation with trapezoidal screw 5, and on the lower surface of trapezoidal nut sliding block 9 and connection shaft seat 7 Bottom surface is slidably matched.
First ushers to seat rolling bearing 12 and the second rolling bearing 10 of usheing to seat is fixedly connected by fastener with connect base 4.
Connect base 4 is fixedly connected under fastener effect with desktop fixed mount 2.
Trapezoidal nut sliding block 9 screws cooperation with trapezoidal screw 5, has latching characteristics.Under the drive that wind 6 rotates, The rotary motion of trapezoidal screw 5, trapezoidal nut sliding block 9 is driven to screw and for linear motion.Trapezoidal nut sliding block 9 is limited to first band Seat rolling bearing 12 and second is usherd to seat and moved along a straight line back and forth between rolling bearing 10.Sold in the second bearing pin 11, connecting rod 3, first Under the collective effect of hinge, desktop fixed mount 2 between axle 8, connection shaft seat 7, desktop 1 and desktop fixed mount 2 etc., table The change of pitch angle of panel 1 is adjusted.
Once the rotation of wind 6 stops, the motion that screws of trapezoidal screw 5 and trapezoidal nut sliding block 9 also stops immediately, Under trapezoidal screw 5 and the self-locking action of trapezoidal nut sliding block 9, the transfixion of desktop 1, desktop tilt adjustment terminates, in locking State.Even if enforcing or pulling the upper end of desktop 1, even if desktop stress is excessive and damaged, turn as long as wind 6 is no Dynamic, desktop 1 all will be with the remains stationary state of connecting rod 3.
Wind 6 rotationally clockwise, trapezoidal screw 5 are rotated and screwed with trapezoidal nut sliding block 9, trapezoidal nut sliding block 9 Moved towards close to user direction, drive connecting rod 3 to jack desktop 1, the desktop inclination angle (folder of desktop and horizontal plane Angle) incrementally increase;Wind is rotated in an anti-clockwise direction, 6 trapezoidal screws 5 are rotated and screwed with trapezoidal nut sliding block 9, and trapezoidal nut is slided Block 9 moves towards user direction, drives connecting rod 3 to pull desktop 1, desktop inclination angle (angle of desktop and horizontal plane) Progressively reduce.
Because trapezoidal screw 5 and trapezoidal nut sliding block 9 screw, cooperation has self-locking action in itself and self-locking is solid and reliable, Extra locking and unblock parts are not needed, therefore such a study table of design of the present utility model is simple in construction, and adjust Simple to operate laborsaving, what is more important tilt adjustment also stable and continuous, scope is big.Both the tune of that mechanism had not been adjusted discontinuously Section is discontinuous, abnormal sound when will not produce unblock during adjusting again or lock.
Meanwhile as long as being of convenient length for desktop tilt adjustment connection shaft seat installation site and connecting rod, can reach 90 °, I.e. 0-90 ° continuously adjusts.During desktop tilt adjustment, it is only necessary to which singlehanded to shake wind as requested, hand power is at 20 Ns It is easily comfortable below, the extra button press of another hand or spanner or other simultaneously operatings are not needed at all.So operate It is simple easily, without added burden, meet the related request of ergonomic.
Although the utility model is disclosed as above with preferred embodiment, the utility model is not limited to this.Any Art personnel, do not departing from spirit and scope of the present utility model, can make various changes or modifications, therefore this practicality New protection domain should be defined by claim limited range.
